If you are on a budget travel but still need comfortable and enjoyable staying rather than mix-dorm bed, you gotta take a look at Thawatchai's place. His place is near the BTS Udom Suk, which made it easy for travelling ( took about 20-25min to Siam Paragon by BTS, and also there was likely a chance for you to get a seat in BTS ), and a lot of streetfood around. You will have everything you need for every personal demands: pool, gym, library, kids' room, and a well-facilitated room.
The thing i love most is the view looking out to the city from bed. The room is clean, lovely and feel like home.
Although we didn't have a chance to meet Thawatchai directly but he is very kind and helpful, it's very quick and easy to reach him via imess. His guide to check-in and check-out are very clear and detailed.
Definitely come back next time !
